.The invention `relates to lever. lcontrolled Vbolts for doors andhas for `its object to pro- Tide a Vdevice of .this `character comprising a single pivotedlever havingconnections .with

-. the door bolts,

for instance the upper and `,lo-wer bolts andby pressure, on `the .lever the bolts are vsimultaneo usly moved to .open

^ ziposition. r Ihe device-.isparticularly.adapted s for exit doors of amusement .houses orbuildings -wlieize large crowds of persons collect.

' tion and 1A further object is to the door substantially U ital tcross i.section Yand provide a :easing on -shaped in horizon-V iaving rollers overy which. flexible members connected to the bolts extend, and to p ositioii the pivoted leilel,WhQrGbyitseIidwill be disposed in a recess in the casing between adjacent rollers and in a slidable bolt slidably mounted on the rollers and within the casing positioned whereby it may be moved over the end of the lever within the casing recess for locking said lever against movement.

With the above and other objects in view the invention resides in the combination and arrangement of parts forth,

as hereinafter set shown in the drawing, described and claimed, it being understood that changes in the precise embodiment of the invention may be made withinV the scope of what is claimed without departing from the spirit of the invention.

In the drawing: Figure l is a perspec tive View of a portion of conventional form of door, showing the device applied thereto.

Figure 2 is a vertical view Figure 3 is a horizo transverse sectional through the looking device and a door.

ntal sectional view taken on line 3 3 of Figure 1.

Referring to the drawing the numeral 1 designates a portion of a conventional forni of swinging door and 2 casings secured to said door adjacent its upper and lower ends,

and in which downwardlyr by means o which areslidably mounted bolts 3 are normally forced upwardly and f the coiled springs 4, whereby said bolts are forced into the keepers 5 and 6, carried adjacent the upper and lower ends of the door. of the door by means of tend through the lugs 8,

Secured to the face screws 7, which exis a casing 9, which casing is U-shaped in horizontal cross secspaced rollers 10 and has rotatably mounted therein 11, and over which rollers the flexible members l2 which are connected to the sliding bolts 3 extend and .are guided intlieir, ymovement during; an iiiiboltino' ,orbolting oieration.

,s e. l

Casing 9, is

:provided with la recess 13 into which the transverse portion :lll-

extends and 4to the of the pivoted lever4k 15 ends of vthe transverse yportion l'l the adjaceiitends of the vliexible members l2 are anchored ,at l5. It will bc seenA that when' a pe the handle member handle member will on 'its pivotal pointV Ytransverse portion lof from Ythe recess 13, simultaneous pull on rsoii imparts 17 of the lever l5, said causethe lever to. rock 18, thereby moving the theglever youtwardly consequently impart a ythe'chains 12 and move a push oii the -slidiiigbolts to openV position, mid the `coi-itiniied Y push will `swing the' door .to 4opeii position, which is particularly desirable for exit doors in houses of public gathering,

where in cases of emergency it is necessary to quickly open the It is obvious that doors.

at Vtimes itis desirable to lock the bolts or lever against operation, l and to accomplish this result asliding bolt 19 is slidably mount casing 9 within the ed within theY U-shaped arcuate portions 20 of Vthe casing and which bolt also slidably engages the rollers 10,

thereby utilizing said rollers forguiding means, consequently allowing the device to be cheaply manufactured. The bolt 19 is provided with an outwardly extending iin holding the bolt in ger engaging lug 21. for its closed or open position. The lug 21, when the bolt 19 is in open position is moved into the recess 22 as clearly shown iii Figure l, and when the bolt is in closed or locked position the lug 21 is moved into the recess 23 after a longitudinal movement where its lower end 414. of the lever, and

the recess 23 by a bolt 19. It will be as a whole can of the bolt to a position will overlie the portion the lug is moved into partial rotation of the not-ed that the casing 9 be stamped Vfrom a single piece of material, consequently the cost lof the casing is reduced to a minimum.

From the above it will be seen a controlded for multiple bolts ling means is provi whereby the bolts may operated by a single a single movement of the bolt means is provided,

ers within the casin the pivoted lever against movement w The invention hav is claimed as new an be simultaneously operating lever and by lever, and sliding guidable on the rollg. for cooperating with for locking the same hen desired. ing been set forth what d `useful is:
